Showing 25 of 43 transactions.
Open-market purchases and sales (Form 4 codes P and S) by officers, directors and 10% owners, by transaction date, from 2025-12-17 to 2026-04-16. Excludes option exercises, grants, gifts and tax withholding. Amended filings replace the originals; joint filings count once. Foreign private issuers do not file Form 4. Many insider sales are pre-scheduled (10b5-1 plans) and are not by themselves a sign of wrongdoing.
"As discussed in Note 1 to the financial statements, the Company has incurred significant losses and negative cash flows from operations since inception and will not have sufficient cash and other resources on hand to sustain current operations or meet obligations as they become due, that raise substantial doubt about the Company's ability to continue as a going concern."
Quoted from the filing. Source
The filing states that substantial doubt exists about the company's ability to continue as a going concern: it may not have enough cash to last the next 12 months. Expect dilution, debt deals or worse. An auditor's going-concern paragraph is the strongest form of this warning.
